Creating a Rosette Transfer Curve

To simulate draping in producibility, you can create and edit a curve that indicates where a chosen orientation is on the selected reference surface. The curve is computed from the rosette transfer type information, or from automatic inputs when created within a producibility command.

Before you begin:
  • Older models must be upgraded to the new rosette feature.
  • Editing a rosette transfer curve requires access to a Composites app.
  1. Activate the geometrical set where you want to create the rosette transfer curve.
  2. From the Review section of the action bar, click Rosette Transfer Curve .
  3. Select a rosette.
  4. Select the surface where the curve is created.

    In most cases, it is the reference surface.

  5. Select a passage point of the curve.
    A rosette transfer preview is attached to this point.
  6. Select an orientation.
  7. Define a Maximum Deviation angle.
  8. Click Preview.
    • The Rosette is transferred at the selected point.
    • A point-direction geodesic line is created at the selected point in the direction given by the transferred rosette at the selected point. Its length depends on the surface size.
    • The Rosette is transferred at the end of the geodesic line. A new geodesic line is computed from there.
    • These two steps are repeated until the geodesic line is stopped by a surface boundary, or intersects another geodesic line, or itself. This could be the case on a cylindrical surface.
    • The process is repeated in the other direction from the selected point.
    Note: The curve creation stops if:
    • The Rosette cannot be transferred at the end of a geodesic line.
    • Geodesic lines cannot be created.
    • The deviation between the end point of a geodesic line and the transferred Rosette at this point exceeds the Maximum Deviation.

    In such cases, the curve is created with the computed points and an update warning is displayed.

A Rosette Transfer Curve is created in the current geometric set. It can be used as any other curve on surface.
